Question

A meteorite that has a mass equal to 30.8 tonne (1 tonne = 1000 kg)
is exhibited in the American Museum of Natural History in New York
City. Suppose that the kinetic energy of the meteorite as it hit
the ground was 584 MJ.
(a) Find the magnitude of the impulse experienced by the meteorite
up to the time its kinetic energy was halved (which took about t =
3.3 s).
_________MN·s

(b) Find also the average force F exerted on the meteorite during
this time interval.
__________MN
